Inspired by http://stackoverflow.com/questions/14644353/get-the-number-of-pages-in-a-pdf-document/14644354

pdfinfo is an unix tool helping extract information from pdf files.

http://linuxcommand.org/man_pages/pdfinfo1.html

You can get page count, title, author..etc via the tool.

First you need to have pdfinfo in your system.

For ubuntu, there's an easy way for doing this:

sudo apt-get install poppler-utils

You can just download the file to your project, or install it via composer:

composer require "howtomakeaturn/pdfinfo:1.*"

Just pass the path to the pdf file to the constructor, and you can get metadata from its properties immediately:

$pdf = new PDFInfo('path/to/the/pdf');
echo $pdf->title; // Get the title
echo $pdf->pages; // Get the number of pages
